Abstract: 247,869. Toronto Type Foundry Co., Ltd., (Assignees of Hitchcock, R.). May 23, 1925, [Convention date]. Pile tables and supports for sheet feeds.- A pile support for an automatic sheet-feeding machine comprises an automatically raised frame in which can be fitted one, two, or three table-like sections which can be used singly or collectively to enable the machine to deal with sheets of different sizes. As applied to a machine in which the sheets are forwarded by a suction roller j, Figs. 2 and 3, as described in Specification 244,402, the frame for supporting the table sections f, f<1> f<11> consists of longitudinal angle members e, and transverse members e', and is carried by chains d which are mounted on sprocket wheels c<1> driven by worm gearing b, b<1> controlled in known manner to keep the pile at constant level. The second table section f<SP>1> is guided and supported by an extension f<3>, which passes under the section f, and abuts against the edge of the angle-iron e as shown in Fig. 5. The end section f<11> is fitted with anglebars f<5> which move over guides f<4> attached to the section f<1> at a distance equal to the thickness of the angle irons. To facilitate access to the pile from the rear, the chains d are mounted in an upright frame of open construction comprising upright members g<1>, g<11>. This frame is provided with a brace g which can be pivoted to one side, as shown in Fig. 3 in dotted lines, to allow of greater accessibility through the frame, if desired. The brace g can be held in the position shown by a spring catch.

Filed: 1932-08-31
Abstract: 396,563. Coin - controlled timing- device. LUNDIN, K. A. E., 96, Saxogade, Copenhagen. Aug. 31, 1932, No. 24322. [Class 27.] Coin-controlled apparatus for permitting the use of a gramophone, radio set, or other article for a predetermined period of time comprises clockwork mechanism coupled with a pivoted coin channel which is normally locked, but which is released by a coin to enable the clockwork to be wound, the winding operation causing the channel to move and release the controlling mechanism of the article to be used.. As shown, the channel 2, pivoted at 3, is locked. by the engagement of a projection 9 thereon with teeth 10 on a pivoted arm 11 carrying a counterweight 12. The channel carries at its upper end a flexible band 4 which is wound on a roller 5 geared to the winding shaft 7 of the clockwork mechanism 6 ; this coupling may be replaced if desired by rack and pinion or other gear. Two coins are inserted through the slot 1 and fall to the bottom of the channel 2, the lower coin 13 releasing the latter by depressing the arm 11. The clockwork may now be wound by the handle 23 through the coupling 7, 18, Fig. 2, the band 4 being wound on the roller 5 and moving the channel 2 about its pivot ; as this occurs, the upper coin 131, which covers an opening 17 in the channel, engages a rod 15 which operates the switch, valve, or other device controlling the article to be used. The rod 15 is connected through a frame 16 with a sliding arm 21 formed with a cam slot 22 which engages a pivoted arm 19 connected with the coupling 7, 18, so that when the clockwork has been wound to a certain extent this coupling is broken, and the clockwork commences slowly to unwind. The channel 2 now moves back into engagement with the arm 11 under the action of a spring 14, the coins having fallen therefrom at the end of the winding operation, and as it does so it engages the frame 16 and restores the rod 15 and the coupling 7, 18 to their original positions.

Abstract: 627,705. Generating combustion products under pressure. BABCOCK & WILCOX, Ltd. Aug. 16, 1946, No. 24419. Convention date, July 3, 1941. [Class 51 (i)] Pulverized fuel is burnt under pressure and the combustion gases are cleaned by separating the coarser ash particles and then separating the dust particles. The cleaned gases are supplied to a gas turbine. Pulverized fuel is fed from a storage bin 25, Fig. 4, alternately to containers 26 and 261. The container in use is closed at the top and the corresponding valve 27 or 27<SP>1</SP> is opened to allow the contents to flow by way of a motor-driven feeder 29 to an injector 32. Air flowing through the injector entrains the fuel and carries it to a burner 7 (Fig. 1, not shown) at the entrance 71 to a combustion chamber 1, Fig. 2. Air is supplied at 17 and passes through the annular space between the outer walls 4 and 41 and liners 16 and 5 ; part of it enters the combustion space through nozzles 10 and the remainder passes by way of outlet connections' 8 to the burner 7. A coiled tube for the circulation of cooling water may be located within the liner 5. Ashes.fall'through,an outlet 19 into a water container 33, Fig. 5, and are carried away by water flowing out through a pipe 38. Steam arising from the quenching of the ashes is condensed by water sprays from atomizers 35. The level of water in the container 33 is kept' constant: by a float 36 controlling a valve 37. Ashes which fail to be carried away are periodically removed from a pocket 40. Combustion gases pass by way of an outlet 20 to a filter identical' with that described in Specification 627,706; [Group XXVIII], for the removal of dust before being used in a gas turbine. An alternative ash removal means comprises a water-jacketed chamber 90 (Fig. 9, not shown) for. cooling the ashes, communicating through a valve with a drum for the reception of the cooled ashes.

The process is especially applicable to compounds of the general formula: <FORM:0956271/C2/1> in which R is hydrogen or acyl, X is keto, acyloxy, hydroxy or halogen, Y is hydrogen or halogen, or X and Y together signify a carbon-carbon double bond.  The acid catalyst is preferably a strong acid, and the rearrangement is preferably effected in an ionising solvent medium, yielding mainly D 15 -16- methyl compounds which are hydrogenated over a palladium catalyst using neutral or basic conditions.  Examples detail the conversion of 3b -acetoxy -16- methyl -5a - pregna-9(11): 16-dien -20- one into 3b -acetoxy -17a - hydroxy -16a - methyl -5a - pregn-9 (11)-en -20- one via the 16:17-oxide, the preparation of 3b -acetoxy -17a - hydroxy- -16- methylene -5a - pregnane-11, 20-dione, 3b -acetoxy-9a , 11b -dichloro -16- methylene -17a - hydroxy -5a -pregnan -20- one, and 3b , 17a -dihydroxy -16a -methyl -5a - pregn-9(11)-en -20- one. 16a -Methyl compounds may be freed from their 16b -methyl epimers by crystallisation or by preferential D-homoannulation of the b -epimer.

Abstract: 536,409. Flotation processes. CAMPBELL, T. P., and JACOBSEN, W. B. Aug. 31, 1939, No. 25014. [Class 82 (ii)] In the purification of substances of natural and artificial origin consisting basically of one .or more readily soluble substances and insoluble earthy constituents as impurities, a pulp is formed by introducing the substances in finely divided condition into a saturated solution of the soluble constituent or one of such constituents and 'is then subjected to froth flotation in the presence of a re-agent having a selective affinity for the insoluble impurities such as a soap formed of a fatty acid such as oleic, lauric or palmitic acids or sodium salts of such acids in amounts up to 0.5 lb. per ton of material treated. An inhibiting or depressing agent such as sodium silicate may also be added especially when the substance to be treated is native rock salt. The froth characteristics of the re-agent may be sustained by introducing a polysaccharide into the solution. As applied to the purification of rock salt, the latter is mixed with saturated brine from the tank 2 and also sodium oleate and sodium silicate and fed to a grinding mill 1, such as a ball mill. The ground mixture is passed into a classifier 3 the overflow passing to a battery of flotation cells 4 in series, formed in two groups 4a, 4b additional re-agent being added only to the series 4c. The tailings from these cells is passed to a gravity separator 5 and the froth passes to a launder 4c and thence to an agitator 6 where it is bleached, the brine therefrom passing to a classifier 7 from which the overflow passes through a filter 8 to a pump 14 which returns the liquor to the tank 2. The liquid from the separator 5 is fed to a classifier 9, the oversize particles passing through a filter 10 to a drier 11, and through a screen 12 and is pulverized finally in a pulverizer 13.
